Upgrade pip with pip2 install --upgrade pip before install flask and other things with pip. It solved for me.

...
RUN apk add -U --no-cache python2 python2-dev py2-pip gcc musl-dev tzdata openssl-dev libffi-dev \
  && pip2 install --upgrade pip \
  && pip2 install --upgrade docker==3.0.1 flask flask-restful pyOpenSSL \
  && apk del python-dev py2-pip gcc

Please reopen the issue, it should be fixed in the repository, too.
Thank you!
